context_page_description: Forrest Highway is a 95-kilometre-long highway in Western Australia's Peel and South West regions, extending Perth's Kwinana Freeway from east of Mandurah down to Bunbury. Old Coast Road was the original Mandurah–Bunbury route, dating back to the 1840s. Part of that road, and the Australind Bypass around Australind and Eaton, were subsumed by Forrest Highway. The highway begins at Kwinana Freeway's southern terminus in Ravenswood, continues around the Peel Inlet to Lake Clifton, and heads south to finish at Bunbury's Eelup Roundabout. There are a number of at-grade intersections with minor roads in the shires of Murray, Waroona, and Harvey including Greenlands Road and Old Bunbury Road, both of which connect to South Western Highway near Pinjarra.
  The settlement of Australind by the Western Australian Land Company in 1840–41 prompted the first real need for a good quality road to Perth. A coastal Australind–Mandurah route was completed by 2 November 1842. Though the road was rebuilt by convicts in the 1850s, its importance was already declining.
context_section_description: Since the 1980s, the state government has been committed to constructing and upgrading the Perth Bunbury Highway, a route along coastal roads, including Old Coast Road south of Mandurah. The ultimate design is for a freeway or expressway-standard road, but with staged construction initially providing a dual carriageway.
